Overview

Bring out the best of your bass tone.

The MXR Bass Preamp combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedal board space. Use it to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. Dial it in just the way you want it and send it straight to the house-pre or post-EQ-with the built-in Direct Out.

The Bass Preamp features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange-from 250hz to 1khz-for extensive tonal flexibility. It's all delivered super clean with high headroom thanks to our own Constant Headroom Technology, and you can use the PRE/POST EQ switch to set whether or not your Direct Out signal is affected by the Bass Preamp's EQ section. And of course, the Bass Preamp features a GROUND LIFT switch in case you encounter ground loop hum.

The Bass Preamp is factory preset to operate in ¼" out buffered bypass and Direct Out active. For players who only want to use the ¼" out, there are two internal switches that disable the Direct Out and ¼" out buffered bypass for true ¼" out bypass mode.
